BRIOK-CONVEYER.

Specification of Letters Patent.

Patented July 29, 1913.

Application filed February 26, 1912. Serial N 0. 679,984.

To all whom it may concern Be it known that I, WALDEMAR BoMrrorr, asubject of the King of Great Britain and Ireland, residing at No. 25Newnham road, l/Vood Green, London, England, have invented a new anduseful Improved Brick- Conveyer, of which the following is aspecification. V i

In manufacturing and hardening bricks containing lime, the bricks arepiled on the platform of a truck, which is run on to rails in a steamingcylinder. By subjecting the bricks to the action of steam inside thehermetically closed cylinder, they are hardened in the customary manner.This being completed, the steaming cylinder is opened and the truck isrun out. The removal of the bricks from the trucks is mechanicallyeffected by means of a special arrangement forming the subject matter ofthis invention, which specially aims at efficiency and reliability inthe action of such brick conveyers, and adaptability of same to allworking conditions.

I will now proceed to describe my invention more fully, reference beinghad to the accompanying drawings, in which Figure 1 shows an elevationof the improved brick conveyer. Fig. 2 illustrates a modifiedconstruction of the truck lifting device. The truck a, on which thebricks to be hardened in the steaming cylinder are piled in the usualway, runs on rails b which lead from the steaming cylinder to theconveyer, crossing one or more turn tables on the way, as required.

The conveyer for mechanically shifting the bricks from the floor of thetruck or onto the floor of the transport wagon 0 comprises a motor dpreferably an electromotor, a winch e, to be driven from the motor (Z bythe belt f and suitably dimensioned power transmitting gear, and ahauling member g, to be placed behind the pile of bricks on the truck aand to be detachably secured at both its ends to the two ropes 7b of thewinch e, which ropes extend over the wagon c. When the floors of thetruck a and of the transport wagon 0 lie in the same horizontal planeclose together, the winch e, through the intermediary of the haulingmember 9, pulls the entire load of bricks from the truck a onto thetransport wagon c, the hauling member 9 possessing a bearing surface ofsufiicient area for engaging the base of the pile of the bricks in thefull length I and to such a height, that the pile is sustained in itsoriginal condition While being shifted.

A strong bolt 2' for detachably securing each of the two ropes h of thewinch e to the hauling member 9 is attached to each end of the latter,said bolt extending the full width of the pile on the truck a, asinclicated in Fig. 1. By using such bolts i close to the two end facesof the pile of bricks to be shifted, protection is afforded againstbreaking or injuring the individual bricks of the pile on starting thehauling action. The bolts 2' further serve for detachably securing aboard or plate 70 thereto, said board or plate It being placed at thefront of the pile to be shifted and close thereto, as indicated inFig. 1. The pile of bricks is thus tightly inclosed on all four sidesand safeguarded against loosening at the base while being conveyed. Thedetachable connection between the bolts i and the hauling member 9 atthe one end and the board or plate 70 at the other end may be effectedin any suitable and convenient manner. In actual practice the floor ofthe truck a lies much below the floor of the transport wagon c if bothstand on the same base, the reason for this difierence in height beinthat the trucks are built as low as possib e, so that when run into thesteaming cylinder sufficient space is granted by the latter for forminga big pile on the floor of the truck. For leveling the floors of thetruck a and of the transport wagon c, which is necessary to enable thepile of bricks on the former to be shifted as an unbroken or undisturbedentity onto the latter, I employ an elevator Z adapted to raise thetruck a to the required height. This elevator Z comprises a floor orplatform m carrying a portion of the rails to be lifted therewith,supports for the floor and the elevator mechanism. According to Fig. lthe floor m is attached to vertical screw spindles n. These screwspindles n, which are firmly mounted in suitable bearings at theunderside of the floor, engage the internally screw-threaded naves oftoothed wheels 0, revolubly mounted, but secured against aXialdisplacement in bearings p firmly anchored in a well 9 in the groundbelow the floor m. The toothed wheels 0 mesh with an intermediatetoothed wheel r mounted upon the vertical shaft 8, which is suitablysupported in the well 9. On the lents to the structure set forth.

shaft 8 is keyed a bevel wheel 25, which meshes with a bevel wheel afixed on the horizontal shaft 1). This shaft 1; is suitably supported inthe well 9 and enters, by passing through a channel 10, an adjacent wellm affording accessory bearings for supporting it. In the well as arekeyed to the shaft 1) fast and loose pulleys 7 connected by belts withthe fast and loose pulleys on a power driven shaft 2:. If necessary ordesirable any other suitable power transmission gear may be interposedbetween the drive shaft 2 and the driven shaft 4;. It is further to beobserved that a worm gear may be substituted for the elevating members712, a described. By operating the elevator the floor m, with the loadedtruck a resting thereon, is smoothly raised until it registers flushwith the floor of the transport wagon 0 placed stationary between it andthe winch e.

To insure a tight closure of the floor of the truck a against the floorof the trans port wagon 0, the floor of the truck a may carry a platformm movable on rollers m toward and away from the transport wagon. Thefloor of the truck a having been leveled in regard to the floor of thetransport wagon 0, the pile of bricks on the former may be shiftedsmoothly onto the latter by means of the hauling member 9 actuated bythe winch 6.

According to Fig. 2 the floor m of the elevator rests in a framestructure 2 movable up and down in the well 9 and preferably guided inits movements by rollers 3. The frame structure 2 is supported on adoublearmed lever l, the second arm of which carries a sleeve 5internally screw-threaded for engagement with a vertical screw spindle6. This screw spindle 6 is revolubly mounted in bearings which secure itagainst axial displacement. A bevel wheel 7 fast at the top end of thescrew spindles 6 meshes with a bevel wheel 8 keyed on the driving shaft9, so that the rotation of the latter smoothly raises or lowers thefloor m, as may be 'required under the prevailing circumstances.

While I have shown in the accompanying drawings the preferred form of myinven tion, it will be understood that I do not limit myself to theprecise form shown, for many of the details may be changed in form orposition without affecting the operativeness or utility of my invention,and I therefore reserve the right to make all such modifica tions as areincluded within the scope of the following claims, or of mechanicalequiva- To indicate such a mechanical equivalent it is pointed out thata hydraulic jack may be employed for elevating the trucks.

The conveyers and the elevator are to be suitably housed and astationary roof is preferably to be built over the lifting and conveyingground. I

\Vhat I do claim as my invention, and desire to secure by LettersPatent, is:

1. In apparatus for sliding a pile of bricks having a rectangular baseofi the surface of one truck on to that of another, the combination of asource of motive power, a winch driven from the said source, a straighthauling member adapted to engage the flat back side of the base of thepile, two bolts detachably attached to the said member extending closeto the respectively opposite ends of the said base and two ropes each atone end secured to the winch and at the'other end detachably secured toone of the bolts.

2. In apparatus for sliding a pile of bricks off the surface of onetruck on to that of another, the combination of a source of motivepower, a winch driven from the said source, a straight hauling memberadapted to engage the flat back side of the base of the pile, a straightmember engaging the flat front side of the base of the pile, two boltsdetachably connecting together the two said members extending close tothe respectively opposite ends of the said base and two ropes each atone end secured to the winch and at the other end detachably secured toone of the bolts.

3. In apparatus for sliding apile of bricks having a rectangular baseoff the surface of one truck capable of being raised and lowered on tothat of a transport wagon-standing always at the same level, thecombination with a platform capable of being raised and lowered, railson this platform on to which the truck is received, raising and loweringmeans for this platform to bring the surface of the truck on thisplatform to the level of that of the transport wagon, a source of motivepower, a winch driven from the said source, a straight hauling memberadapted to engage the flat back side of the pile, a straight memberengaging the flat front side of the base of the pile, two boltsconnecting together the two said members extending close to therespectively opposite ends of the said base, and two ropes extendingover the transport wagon and each at one end secured to the winch and atthe other end secured to one of the bolts.
